// IMPORTANT! // Please, when your changes cause failures in bytecodeText tests for 'for' loops, // examine the resulting bytecode shape carefully. // Range and progression-based loops generated with Kotlin compiler should be // as close as possible to Java counter loops ('for (int i = a; i < b; ++i) { ... }'). // Otherwise it may result in performance regression due to missing HotSpot optimizations. // Run Kotlin compiler benchmarks (https://github.com/Kotlin/kotlin-benchmarks) // with compiler built from your changes if you are not sure. const val M = Char.MIN_VALUE fun f(a: Char): Int { var n = 0 for (i in a downTo M) { n++ } return n } // 0 iterator // 0 getStart // 0 getEnd // 0 getFirst // 0 getLast // 0 getStep // 2 IF // JVM_IR_TEMPLATES // 5 ILOAD // 3 ISTORE // 1 IADD // 0 ISUB // 1 IINC
